How to enable linear output on PC. How to enable line input. What is a line input for?

Instructions

The line input is usually turned on by default, and if you do not hear sound when connecting a device, then you need to make sure of the following:

Are drivers installed on yours?

Is the line-in input set to line-in (for some sound card utilities)?

Is it output in the mixer?

As for the drivers, they must be supplied on a disk along with the sound card, or be pre-installed on yours (if it is new). Otherwise, you need to find out the sound card model and download the necessary driver from the Internet.

For some equipment, along with drivers, special utilities, advanced Windows mixer. For example, Realtek. In such cases, you need to run this program and see if the line input is activated. The shortcut to this program is usually located in the system tray next to the clock. In the settings window that opens, check the box or click the “enable” button next to the linear icon (blue input). After this, he must. In the same program, open the mixer or go to the appropriate settings section. Here you need to make sure that the volume control corresponding to the line input is raised. Otherwise, pick it up.

If you have additional utilities, or you don’t know how to launch them, you can use the system mixer. It is located at:
For Windows XP: Start > Settings > Control Panel > Sounds and Audio Devices > Tab: Volume > Advanced…

The system mixer window will open. Find the inscription “Lin. entrance". Below it you will see a volume scale and a checkbox with the inscription “Off”. The checkbox next to this inscription must be unchecked, and the volume slider must be moved to the volume level you require.
For Windows 7: Start > Control Panel > Hardware and Sound > under “Sound”, click: “Volume”. Next, under the words “Line input”, raise the volume slider to the required level.

Linear entrance in a computer audio device it is used mainly for connecting microphones. Its configuration is carried out without using any special utilities.

Instructions

Make sure that the driver for your sound card has been installed correctly. To do this, open the Hardware Installation Wizard; if your sound adapter is not listed in devices without software, then everything was installed correctly.

If the wizard prompts you to install the device driver, insert the software disc into the drive, or specify the path to the folder with drivers on your hard drive. You can also use the Internet connection. After installing the driver, restart your computer.

How to configure the linear input?

Master's answer:

The line input is used on a computer to connect a microphone to it. If you plan to use the microphone as an intercom or audio recording device, you will need to configure it correctly. Configuration is carried out using standard utilities available in any version of the OS.

First of all, you need to check the drivers for your sound card. They must be installed correctly and have the latest version. Otherwise, you simply won't be able to connect the microphone. To do this, you need to open “Device Manager” and find your sound card there. If it works fine, then the driver is installed correctly.

If the drivers are missing, the wizard will prompt you to install them. To do this, you need to place the software disc in the drive or specify the path to the folder where the driver installation file is stored. You can also use the Internet to search. After the drivers are successfully installed, you will need to restart your computer.

Find the connector on your sound card where you will connect the microphone. According to the standard, it should be painted pink. There should be a drawing of a microphone next to it. If there is no marking, try to find a diagram of your device on which it will be marked. Plug your device into it and check if it works. Next, you will need to configure the line input.

On the “Toolbar”, find the “Sounds and Audio Devices” item. To start setting up, go to the “Audio” tab. In the audio recording section, find the device you recently connected and open its volume menu. Adjust the mixer and microphone settings as desired. On the “Advanced” menu tab, find the item that is responsible for increasing the microphone sensitivity. Check the box there and configure the tone of your device. Please note that the higher the sensitivity, the better the sound quality, but the more extraneous noise the microphone will pick up.

If you plan to use the microphone through a special program, then you will need to configure it directly in the program itself. To do this, launch the application, be sure to connect the microphone. In the main menu, find the “Settings” item and open the settings window. Each program offers its users special customization options, but the basic parameters should be the same for both standard and special utilities.

And most importantly, before setting up, be sure to check the functionality of the microphone and the condition of its cable.

If you have headphones with a microphone and speakers, it's tempting to connect both devices and use them depending on the time of day without having to constantly plug and unplug.
If your audio system supports multi-channel audio (most often, Realtek HD Audio is used everywhere now) - this is not difficult to do. The solution is to switch the computer's audio system to multi-channel (quadraphonic) mode and reassign the properties of the connectors on the computer through the audio driver settings panel.

I'll show you how to do this using the example of the most popular operating system, Windows XP. In Windows 7 and 8 everything is also simple.

Modern desktop computers usually have three audio connectors on the back panel and two on the front. Often the connectors on the front panel are not connected and we will not consider them.

The connectors on the rear panel have different colors:
blue - linear input;
green - line output (headphone output);
red - microphone input.

First of all, go to the Control Panel and click the “Sound and Audio System” button (in other operating systems just “Sound”). Select the tab or "Audio" and in it "Play audio". You can quickly get to this place by right-clicking on the system gray speaker icon at the bottom right of the panel near the clock and selecting “Adjust audio settings.”

Then launch the Realtek HD Audio Manager by right-clicking on the orange speaker icon on the panel next to the clock and selecting "Audio Manager". Click on the wrench button in the "Audio Inputs/Outputs" tab and check the "Connect automatic pop-up dialog for a turned on device" checkbox. Now, when you plug cables into the audio connectors, the system will prompt you to choose what exactly you plugged there. You also need to select “4CH speakers” from the drop-down list above the audio system testing picture.

Then, in turn, connect the green headphone connector to the green computer connector, the red microphone connector to the red computer connector, and the speaker audio cable to the blue computer connector (you don’t need to turn on the speakers yet). At the same time, in the pop-up window, indicate with a tick which device you connected.
For the green connector, select “headphone output,” for the blue connector, “output to the front speakers” (or vice versa), and for the red connector, select “microphone input.”

That's all! Now you can check - the sound will come from both the speakers and headphones at the same time! In the evening, you can turn off the speakers without disconnecting them from the computer. Happy listening!

Line In is the input of any device (not just electronic) whose output signal level is proportional to the input level. In other words, this is an input into which the signal (by default) is almost not processed in any way. On computer sound cards, the line input is usually a blue jack connector. Used to connect a guitar, CD player, radio and other devices to the sound card, the output signal of which does not require additional processing.

Are drivers installed on your sound card?

Is the line-in input set to line-in (for some sound card utilities)?

Is its volume turned up in the mixer?

The system mixer window will open. Find the inscription “Lin. entrance". Below it you will see a volume scale and a checkbox with the inscription “Off”. The checkbox next to this inscription must be unchecked, and the volume slider must be moved to the volume level you require. For Windows 7: Start > Control Panel > Hardware and Sound > under the “Sound” inscription, click: “volume settings”. Next, under the words “Line input”, raise the volume slider to the required level. Tip added on January 10, 2012 Tip 2: How to output a line input Adding a line input to an audio device will allow you to use it as an active speaker system for a computer. You can listen to the signal from the sound card, for example, through a receiver or radio.

Instructions

Line In is the input of any device (not just electronic) in which the level of the output signal is proportional to the level of the input. In other words, this is an input that gets into the one where the signal (by default) is not processed in any way. On computer sound cards, the line input is usually a blue jack connector. Used to connect a guitar, CD player, radio and other devices to the sound card, the output signal of which does not require additional processing.

Instructions

1. The line input is usually turned on by default, and if you don’t hear sound when you connect the device, you need to make sure in the future: - are the drivers installed on your sound card? - is the line input set as linear (for some sound card utilities)? - is it disabled? its volume in the mixer?

2. As for the drivers, they must be supplied on a disk along with the sound card, or be pre-installed on your computer (if it is the latest). Otherwise, you need to find out the sound card model and download the required driver from the Internet.

3. For some equipment manufacturers, special utilities, advanced analogues of the Windows mixer, are installed together with the drivers. Let's say Realtek. In such cases, you need to run this program and see if the line input is activated. The shortcut to this program, as usual, is located in the system tray next to the clock. In the settings window that opens, check the box or click the “enable” button next to the line input icon (blue input). After this, it should turn on. In the same program, open the mixer or go to the appropriate settings section. Here you need to make sure that the volume control corresponding to the linear input is raised. Otherwise, raise it.

4. If you do not have additional utilities installed, or you do not know how to launch them, you can use the system mixer. It is located at: For Windows XP: Start > Settings > Control Panel > Sounds and Audio Devices > tab: Volume > Advanced...The system mixer window will open. Find the inscription “Lin. entrance". Below it you will see a volume scale and a checkbox with the inscription “Off”. You need to uncheck the checkbox next to this inscription, and move the volume slider to the volume level you need. For Windows 7: Start > Control Panel > Hardware and Sound > under the “Sound” inscription, click: “volume settings”. Next, under the words “Line input”, raise the volume slider to the desired level.

Adding linear entrance to the audio device will allow you to use it as a powerful speaker system for your computer. You will be able to listen to the signal from the sound card, say, through a receiver or radio.

Instructions

1. Unplug the device you want to turn into computer speakers. Open its case. Drill a hole in the back wall for the cable through which the sound signal will be sent.

2. Take headphones whose speakers are damaged, but the cable is intact. Cut off the speakers and tin the wires going to them. Do not use a lighter or a knife to clean them - in the first case they may stop tinning, and in the second they will be damaged. Press them against a piece of wood with a soldering iron richly coated with rosin, and the insulation will be removed from the wires without damaging them. After this, tin them as usual.

3. Thread the cable through the hole in the housing made in step one. Tie it with a knot on the inside so as not to accidentally pull it out. Leave a sufficient length of cable inside. Combine the yellow or gray wires together and connect to the common wire of the audio device. Find the volume control in it. Connect the blue or green wire to the input of the volume control of one of the channels through a 0.1 microfarad capacitor, and the orange or scarlet wire through the same capacitor to the input of the control of the other channel. If the device is monophonic, connect only one of the wires, and isolate the 2nd (or even do not strip or tin). In this case, only one capacitor is required.

4. Assemble the audio device, set the volume control to zero, connect it to the computer and the network, start playing some sound, and then set the controls to the desired volume. On the device itself, select a mode in which the amplifier is turned on, but no signal from the built-in sources is received. If the monitor is a tube monitor and the receiver or radio speakers do not have magnetic shielding, install the device away from the monitor. Also, do not place magnetic storage media near it.
